Example Embodiment
[0019] Example: The present invention includes two hollow round steel pipe arch ribs 1, a hollow round steel pipe tie beam 2 and a cross brace 5. The cross brace 5 is welded between the two hollow round steel pipe arch ribs 1. The beam 2 is welded with a cross beam 6 and also includes an arch foot connecting device 4. The two ends of the hollow round steel pipe arch rib 1 and the two ends of the hollow round steel pipe tie beam 2 form a rigid knot through the arch foot connecting plate, and the hollow circle A truss web member 3 is connected between the abdomen of the steel tube arch rib 1 and the hollow round steel tube tie beam 2. The steel bridge deck 9 is continuously laid on the full bridge above the cross beam 6, the steel bridge deck 9 is welded to the tie beam 2 longitudinally, and an I-shaped rib beam 7 is vertically arranged between the cross beam 6 and the steel bridge deck 9, so A U-shaped rib beam 8 is transversely provided at the bottom of the steel bridge deck 9,...
